Rm. Xi et al., NEW LINEAR-TYPE TETRANUCLEAR COMPLEX, [(CP(ASTERISK)RH(MU-SME)(3)MO(O)(2))(2)(MU-O)] (CP(ASTERISK)=ETA(5)-C(5)ME(5)), Chemistry Letters, (2), 1994, pp. 323-326
A mixed metal tetranuclear complex with two Mo-VI(mu-SMe)(3)Rh-III gro
ups, [{Cp Rh(mu-SMe)(3)Mo(O)(2)}(2)(mu-O)] has been obtained from the
reaction of the triple-cubane type oxide cluster [(CpRh)(4)Mo4O16] w
ith MeSH. The complex has been characterized by X-ray analysis and var
iable-temperature H-1 NMR spectroscopy. The latter has revealed that t
he complex exists as a mixture of isomers which show interconversion d
ue to the inversion at the pyramidal sulfur center.
